"I STATES;

WALL CONSTRUCTION.

Application filed. March 16, 1923.

To all whom it may concern:

Be it known that 1, CHARLES V. PInnsoN, a citizen of the United States, residing at- Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Wall Constructions, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to wall construction and has particular reference to a hollow Wall made up of concrete blocks laid one upon the other as is now commonly practiced.

From an architectural standpoint there is a certain degree of monotony in the eX- ternal appearance of a concrete wall con structed with the ordinary blocks now used for the purpose, and one object of my present invention is to employ a header block of special design Which when used in the construction of a wall as hereinafter described will produce a Flemish bond efiect and eliminate the undesirable appearance of the ordinary concrete wall.

Still another object of the invention is to increase the dead air space intermediate the sides of the wall as much as possible, and to have that air space break the connec tion between the ends of the blocks, they being laid up in mortar as is common, it being well known that heat and cold will penetrate through the mortar much more quickly than through the concrete.

Another object of the invention is to pro duce a novel form of corner block so that the architectural design of the wall will not be broken at the corners thereof.

Still other objects and advantages of the invention will appear in the further description thereof, and referring particularly to the accompanying drawing forming part of this application in which like reference characters indicate like parts:

Figure 1 is a side elevation of a portion of a wall made up of my improved concrete blocks;

Figure 2 is a top plan view of the same, showing the improved corner blocks, and

Figure 8 is a plan view of the corner blocks adjacent those shown in Figure 2.

The stretcher blocks are illustrated at 1, and in the construction of a wall they are used in pairs, being spaced apart the desired distance thus providing air space therebetween, and adjacent their ends is placed the header blocks 2, which are of general;

Serial No. 625,480.

til-shape the distance between their legs being equal to the distance between the stretcher blocks, so that the-air space will be continuous and break the connection between the header and stretcher blocks.

The header and stretcher blocks are thus alternated in the construction of the wall until the corner is reached, Where I employ a special two part corner block, the part 3 of which is much similar to the header 2, except that one leg is slightly longer than the other, and the part l of the corner block is substantially L-shaped, the shorter side of which is equal to the width of the header 2. Thus when the corner blocks are alternately laid as illustrated in Figures 2 and 3, the external appearance will be in accord with the appearance of the balance of the wall.

it will be readily apparent to those versed in the art that these blocks as illustrated may be readily molded by pouring of the concrete, thus making a more impervious and durable block for such a wall, and one less liable to conduct moisture than a dry block wall. Also there is a continuous vertical air space in this type of wall thus having all the advantages of a hollow tile wall, but being able to pour the blocks of concrete permits of much cheaper construction as will be obvious. The header blocks, when alternated in adjacent layers of the wall to fur-- nish the Flemish bond effect, also serve as a center bond for the stretcher blocks directly above and below same.

Having thus described my invention,what

I claim and desire to secure by Letters Pat ent, is:

1. A hollow wall comprising spaced stretcher blocks bonded by U-shaped header blocks, the legs of the header blocks being in contact with the ends of the adjacent stretchers.

2. A hollow wall corner construction comprising U-shaped and L-shaped corner blocks, and stretcher blocks, said stretcher blocks being arranged in spaced relation,

said U-shaped blocks having one leg longer than the other, the longer leg coacting with the inner stretcher and the shorter leg coacting with the L-shaped blocks to complete the outer wall surface.

3. A hollow wall comprising spaced stretcher blocks bonded by U-shaped header i 4. A hollow Wall comprising spaced stretcher blocks bonded by a header block having a cut-away portion therein, said cutaway portion forming a continuation of the space intermediate of the stretcher blocks.

5. A hollow Wall corner construction C0111 prising spaced stretcher blocks extending 3 into the corner of the'wall, a pair of sub stantially L-shaped blocks coacting with the ends of the stretcher blocks forming an L shaped opening Within the corner.

6. A hollow Wall corner construction comprising four coacting blocks forming an L- shaped space Within said Wall about the corner, the terminals of said space being unequal in distance from the corner.

7. A hollow Wall corner construction comprising four coacting blocks forming an L- shaped space Within said Wall about the corner, the terminals of said space being unequal in distance from the corner, and said blocks being reversible in their assembled relation about the corner.

In testimony whereof I hereunto aflix my signature.

CHARLES V. PIERSON.
